LIS344AL
MEMS inertial sensor 3-axis ultracompact linear accelerometer
Features

Single voltage supply operation
3.5g full-scale

Output voltage, offset and sensitivity are ratiometric to the supply voltage Factory trimmed device sensitivity and offset Embedded self test RoHS/ECOPACK compliant High shock survivability (10000g) The LIS344AL is capable of measuring accelerations over a maximum bandwidth of 2.0kHz. The device bandwidth may be reduced by using external capacitances. A self-test capability allows the user to check the functioning of the system. The LIS344AL is available in Land Grid Array package (LGA) and it is guarantee to operate over an extended temperature range of -40 C to +85 C. The LIS344AL belongs to a family of products suitable for a variety of applications: Mobile terminals Gaming and virtual reality input devices Antitheft systems and inertial navigation Appliance and robotics.
LGA 16 (4x4x1.5mm)

Description
The LIS344AL is an ultra compact consumer lowpower three-axis linear accelerometer that includes a sensing element and an IC interface able to take the information from the sensing element and to provide an analog signal to the external world. The sensing element, capable of detecting the acceleration, is manufactured using a dedicated process developed by ST to produce inertial sensors and actuators in silicon. The IC interface is manufactured using a CMOS process that allows high level of integration to design a dedicated circuit which is trimmed to better match the sensing element characteristics.
